Using end of line in PHP echo string
提问by Ismael
I am trying to write a PHP script that echos a string, but it doesn't recognize the end of line function in there.
我正在尝试编写一个包含echo字符串的 PHP 脚本，但它无法识别其中的行尾函数。
For example,
例如，
echo "thank you \n "
echo "for coming over"
The \nis ignored and it prints the whole line as thank you for coming over.
该\n被忽略，它打印整个行thank you for coming over。
I got the same result for the following to:
对于以下内容，我得到了相同的结果：
echo "thank you " . PHP_EOL.;
echo "for coming over" . PHP_EOL.;

There are different ways to solve that:
有不同的方法可以解决这个问题：
Using Pre-formatted text
使用预先格式化的文本
echo '<pre>'; // pre-formatted text, \n should work
echo "thank you \n ";
echo "for coming over";
echo '</pre>';
Changing the content type
更改内容类型
header('Content-Type: text/plain');
echo "thank you \n ";
echo "for coming over";
You browser will now properly read the output as text.
您的浏览器现在可以正确地将输出读取为文本。
Using the HTML break element
使用 HTML 中断元素
echo "thank you <br>\n ";
echo "for coming over";
So output always depends on what you want to output. Is it text? Is it HTML? Is it some text within HTML? Depending on what you need you should take care on the format and formatting.
所以输出总是取决于你想输出什么。是文字吗？是 HTML 吗？它是 HTML 中的一些文本吗？根据您的需要，您应该注意格式和格式。

If you are doing this in a browser, replace \nwith <br />. The file line breaks are not rendered in an HTML page, unless specified via CSS or if they're enclosed in certain tags. You could also optionally change the file type to text/plain, but I don't think that would be desired.
如果您在浏览器中执行此操作，请替换\n为<br />. 除非通过 CSS 指定或包含在某些标签中，否则文件换行符不会在 HTML 页面中呈现。您还可以选择将文件类型更改为text/plain，但我认为这不是所希望的。

echo "thank you <br>";
echo "for coming over<br>";
and at time of file handling
和文件处理时
echo "thank you ".PHP_EOL."";
echo "for coming over".PHP_EOL."";

Check the source of the web page from browser, there will be a new line. Since in HTML, whitespaces like newline, tabs or spaces are ignored, you can't see them in the browser. You need to use <br />or etc. to print what you want.
从浏览器检查网页的来源，会有一个新行。由于在 HTML 中，诸如换行符、制表符或空格之类的空格会被忽略，因此您无法在浏览器中看到它们。您需要使用<br />或 等来打印您想要的内容。
